title: 3-Amino-4-(1,3-benzoxazol-2-yl)-5-(cyclo-hexyl-amino)-thio-phene-2-carbo-nitrile.
abstract: In the title compound, C18H18N4OS, the cyclo-hexyl ring adopts a chair conformation. The other rings of this compound lie almost in the same plane, with a mean deviation of 0.03 (2) Å from the least-squares plane defined by the 14 constituent atoms. There are intra-molecular N-H⋯N and N-H⋯O hydrogen bonds, as well as inter-molecular N-H⋯N hydrogen bonds, which link the mol-ecules into centrosymmetric dimers.
